do you now have the m50 or m20? some 91's had an m20.Originally Posted by kibosmith
If you have an m20, it's probably not a bad idea, but will need a bigger radiator, relocate battery to backseat, etc. just mostly minor things. Tranny should bolt up, etc, etc.
If you have the m50 now, it's not even worth it. Sure theres an HP gain, but the technology is older and the loss in fuel economy, modern technology, etc just really isn't worth it. Try to get in a nice m52 if thats what your going for.
